Netscape Navigator is a discontinuedproprietaryweb browser, and the original browser of theNetscape line, from versions 1 to 4.08, and 9.x. It was theflagship product of theNetscape Communications Corporation and was the dominant web browser in terms ofusage share in the 1990s, but by around 2003 its user base had all but disappeared.[2] This was partly because of Microsoft's bundling ofInternet Explorer with theWindowsoperating system.[3][4]
The business demise of Netscape was a central premise ofMicrosoft's antitrust trial, wherein the Court ruled thatMicrosoft's bundling ofInternet Explorer with theWindows operating system was amonopolistic and illegal business practice. The decision came too late for Netscape, however, as Internet Explorer had by then become the dominant web browser in Windows.
The Netscape Navigator web browser was succeeded by theNetscape Communicator suite in 1997. Netscape Communicator's 4.x source code was the base for the Netscape-developedMozilla Application Suite, which was later renamedSeaMonkey.[5] Netscape's Mozilla Suite also served as the base for a browser-only spinoff calledMozilla Firefox.
The Netscape Navigator name returned in 2007 whenAOL announced version 9 of theNetscape series of browsers,Netscape Navigator 9. On December 28, 2007, AOL canceled its development but continued supporting the web browser with security updates until March 1, 2008. AOL allows downloading of archived versions of the Netscape Navigator web browser family.[6]
Netscape Navigator was inspired by the success of theMosaic web browser, which was co-written byMarc Andreessen, a part-time employee of theNational Center for Supercomputing Applications at theUniversity of Illinois. After Andreessen graduated in 1993, he moved toCalifornia and there metJim Clark, the recently departed founder ofSilicon Graphics. Clark believed that the Mosaic browser had great commercial possibilities and provided the seed money. SoonMosaic Communications Corporation was in business inMountain View, California, with Andreessen as a vice-president. Since the University of Illinois was unhappy with the company's use of the Mosaic name, the company changed its name to Netscape Communications (suggested by product manager Greg Sands[7]) and named its flagship web browser Netscape Navigator.
Netscape announced in its first press release (October 13, 1994) that it would make Navigator available without charge to all non-commercial users, and beta versions of version 1.0 and 1.1 were freely downloadable in November 1994 and March 1995, with the full version 1.0 available in December 1994.[8] However, two months later, the company announced that only educational and non-profit institutions could use version 1.0 at no charge.[9]
The reversal was complete with the availability of version 1.1 beta on March 6, 1995, in which a press release states that the final 1.1 release would be available at no cost only for academic and non-profit organizational use.
The first few releases of the product were made available in "commercial" and "evaluation" versions; for example, version "1.0" and version "1.0N". The "N" evaluation versions were identical to the commercial versions; the letter was intended as a reminder to people to pay for the browser once they felt they had tried it long enough and were satisfied with it. This distinction was formally dropped within a year of the initial release, and the full version of the browser continued to be made available for free online, with boxed versions available on floppy disks (and later CDs) in stores along with a period of phone support. During this era, "Internet Starter Kit" books were popular, and usually included a floppy disk or CD containing internet software, and this was a popular means of obtaining Netscape's and other browsers.[10] Email support was initially free and remained so for a year or two until the volume of support requests grew too high.
During development, the Netscape browser was known by the code nameMozilla, which became the name of aGodzilla-like cartoon dragonmascot used prominently on the company's web site. The Mozilla name was also used as theUser-Agent inHTTP requests by the browser. Other web browsers claimed to be compatible with Netscape's extensions to HTML and therefore used the same name in their User-Agent identifiers so that web servers would send them the same pages as were sent to Netscape browsers.Mozilla is now a generic name for matters related to theopen source successor to Netscape Communicator and is most identified with the browserFirefox.
When the consumerInternet revolution arrived in the mid-1990s, Netscape was well-positioned to take advantage of it and the influx of new users it brought. With a good mix of features and an attractivelicensing scheme that allowed free use for non-commercial purposes, the Netscape browser soon became thede facto standard, particularly on theWindows platform.Internet service providers and computer magazine publishers helped make Navigator readily available.
An innovation that Netscape introduced in 1994 was the on-the-fly display of web pages, where text and graphics appeared on the screen as the web page downloaded. Earlier web browsers would not display a page until all graphics on it had been loaded over the network connection; this meant a user might have only a blank page for several minutes. With Netscape, people usingdial-up connections could begin reading the text of a web page within seconds of entering a web address, even before the rest of the text and graphics had finished downloading. This made the web much more tolerable to the average user.
Through the late 1990s, Netscape made sure that Navigator remained the technical leader among web browsers. New features includedcookies,frames,[11]proxy auto-config,[12] andJavaScript (in version 2.0). Although those and other innovations eventually became open standards of theW3C andECMA and were emulated by other browsers, they were often viewed as controversial. Netscape, according to critics, was more interested in bending theweb to its own de facto "standards" (bypassing standards committees and thus marginalizing the commercial competition) than it was in fixing bugs in its products. Consumer rights advocates were particularly critical of cookies and of commercial web sites using them to invade individual privacy.
In the marketplace, however, these concerns made little difference. Netscape Navigator remained the market leader with more than 50%usage share. The browser software was available for a wide range of operating systems, including Windows (3.1,95,98,NT),Macintosh,Linux,OS/2,[13] and many versions of Unix includingOSF/1,Sun Solaris,BSD/OS,IRIX,AIX, andHP-UX, and looked and worked nearly identically on every one of them. Netscape began to experiment with prototypes of a web-based system, known internally as "Constellation", which would allow users to access and edit their files anywhere across a network no matter what computer or operating system they happened to be using.[14]
Industry observers forecast the dawn of a new era of connected computing. The underlyingoperating system, it was believed, would not be an important consideration; future applications would run within a web browser. This was seen by Netscape as a clear opportunity to entrench Navigator at the heart of the next generation of computing, and thus gain the opportunity to expand into all manner of other software and service markets.

With the success of Netscape showing the importance of the web (more people were using the Internet due in part to the ease of using Netscape), Internet browsing began to be seen as a potentially profitable market. Following Netscape's lead, Microsoft started a campaign to enter the web browser software market. Like Netscape before them, Microsoft licensed the Mosaic source code fromSpyglass, Inc. (which in turn licensed code fromUniversity of Illinois). Using this basic code, Microsoft createdInternet Explorer (IE).
The competition between Microsoft and Netscape dominated thebrowser wars. Internet Explorer,Version 1.0 (shipped in the Internet Jumpstart Kit in Microsoft Plus! ForWindows 95[15]) and IE,Version 2.0 (the first cross-platform version of the web browser, supporting bothWindows andMac OS[16]) were thought by many to be inferior and primitive when compared to contemporary versions of Netscape Navigator. With the release ofIE version 3.0 (1996) Microsoft was able to catch up with Netscape competitively, withIE Version 4.0 (1997) further improvement in terms of market share.IE 5.0 (1999) improved stability and took significant market share from Netscape Navigator for the first time.
There were two versions of Netscape Navigator 3.0, the Standard Edition and the Gold Edition. The latter consisted of the Navigator browser with e-mail, news readers, and aWYSIWYG web page compositor; however, these extra functions enlarged and slowed the software, rendering it prone to crashing.
This Gold Edition was renamedNetscape Communicator starting with version 4.0; the name change diluted its name-recognition and confused users. Netscape CEOJames L. Barksdale insisted on the name change because Communicator was a general-purposeclient application, which contained the Navigatorbrowser.
The aging Netscape Communicator 4.x was slower thanInternet Explorer 5.0. Typical web pages had become heavily illustrated, often JavaScript-intensive, and encoded with HTML features designed for specific purposes but now employed as global layout tools (HTML tables, the most obvious example of this, were especially difficult for Communicator to render). The Netscape browser, once a solid product, becamecrash-prone andbuggy; for example, some versions re-downloaded an entire web page to re-render it when the browser window was re-sized (a nuisance to dial-up users), and the browser would usually crash when the page contained simpleCascading Style Sheets, as proper support for CSS never made it into Communicator 4.x. At the time that Communicator 4.0 was being developed, Netscape had a competing technology calledJavaScript Style Sheets. Near the end of the development cycle, it became obvious that CSS would prevail, so Netscape quickly implemented a CSS to JSSS converter, which then processed CSS as JSSS (this is why turning JavaScript off also disabled CSS). Moreover, Netscape Communicator's browser interface design appeared dated in comparison to Internet Explorer and interface changes in Microsoft and Apple's operating systems.
By the end of the decade, Netscape's web browser had lost dominance over the Windows platform, and the August 1997 Microsoft financial agreement to invest $150 million inApple Computer required that Apple make Internet Explorer the default web browser in new Mac OS distributions. The latestIE Mac release at that time was Internet Explorer version 3.0 for Macintosh, but Internet Explorer 4 was released later that year.
Microsoft succeeded in havingISPs and PC vendors distribute Internet Explorer to their customers instead of Netscape Navigator, mostly due to Microsoft using its leverage from Windows OEM licenses, and partly aided by Microsoft's investment in making IEbrandable, such that a customized version of IE could be offered. Also, web developers usedproprietary, browser-specific extensions in web pages. Both Microsoft and Netscape did this, having added many proprietary HTML tags to their browsers, which forced users to choose between two competing and almost incompatible web browsers.

In March 1998, Netscape released most of the developmentcode base for Netscape Communicator under anopen source license.[17] Only pre-alpha versions ofNetscape 5 were released before the open source community decided to scrap the Netscape Navigator codebase entirely and build a new web browser around theGeckolayout engine which Netscape had been developing but which had not yet incorporated. The community-developed open source project was namedMozilla, Netscape Navigator's originalcode name.America Online bought Netscape; Netscape programmers took a pre-beta-quality form of the Mozilla codebase, gave it a new GUI, and released it as Netscape 6. This did nothing to win back users, who continued to migrate to Internet Explorer. After the release of Netscape 7 and a long public beta test, Mozilla 1.0 was released on June 5, 2002. The same code-base, notably the Gecko layout engine, became the basis of independent applications, includingFirefox andThunderbird.
On December 28, 2007, the Netscape developers announced that AOL had canceled development of Netscape Navigator, leaving it unsupported as of March 1, 2008.[18][19] Archived and unsupported versions of the browser remain available for download.
Netscape's contributions to the web includeJavaScript, which was submitted as a new standard toEcma International. The resultantECMAScript specification allowed JavaScript support by multiple web browsers and its use as across-browser scripting language, long after Netscape Navigator itself had dropped in popularity. Another example is the FRAME tag, which is widely supported today, and that has been incorporated into official web standards such as the "HTML 4.01 Frameset" specification.
In a 2007PC World column, the original Netscape Navigator was considered the "best tech product of all time" due to its impact on the Internet.[20]
